To solve the multiplication problem 31 x 19 using the expanded algorithm, you can follow these steps:

Step 1: Write the two numbers, 31 and 19, one below the other in a column.

31
x 19

Step 2: Start with the ones place of the bottom number (9 in this case) and multiply it with each digit in the top number. Write the products below each digit of the top number.

31
x 19
-------
31
279

Step 3: Move to the tens place of the bottom number (1 in this case) and repeat the process, but this time shift the products one place to the left.

31
x 19
-------
31
279
-------
310

Step 4: Add up all the products to get the final answer.

310

So, 31 x 19 = 310.

You can double-check this answer by using a calculator or doing the multiplication the long way.
